Abstract
Abstract A solid oxygen-ion electrolyte cell electrically and chemically coupled with a thermal power generator is described wherein the generation of hydrogen is coulometric with respect to current received by the solid oxygen-ion electrolyte cell from the power generator. Hydrocarbon fuel is consumed in the thermal power generator to produce steam and generate electrical power. Both of these products are supplied to the solid oxygen-ion electrolyte cell wherein dissociation of the steam for the generation of hydrogen gas is carried on. A particular application of this invention described is the conversion of coal to ammonia.
